Description

寻呼消息发送的方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及一种寻呼消息发送的方法和装置。
背景技术
在新无线(new radio，NR)中，终端设备(user equipment,UE)所处的状态包括三种，无线资源控制空闲态(radio resource control_idle，RRC_IDLE)态、RRC非激活(RRC_INACTIVE)态及RRC连接态(RRC_CONNECTED)态。当网络有下行数据需要发往处于RRC_IDLE或RRC_INACTIVE态的UE时，网络需要先通过寻呼(paging)流程来寻呼UE，以通知该UE建立或恢复RRC连接，然后才能进行数据传输。
处于RRC_IDLE或RRC_INACTIVE态的UE支持使用非连续接收(discontinuous reception，DRX)的方式来接收paging消息以降低功耗。RRC_IDLE或RRC_INACTIVE态的UE在每个寻呼周期内的某个特定寻呼机会(paging occasion，PO)上去尝试接收寻呼无线网络临时标识(paging radio network temporary identifier，P-RNTI)加扰的DCI；基站收到核心网或无线接入网设备触发的寻呼后，会向UE发送用于调度寻呼消息的DCI，UE根据该DCI接收寻呼消息。
若在某个PO处UE没有监听到P-RNTI加扰的DCI，则UE在该PO的监听会导致浪费功耗。在NR系统中计划引入第一消息，该第一消息可以称为寻呼提前指示(paging early indication,PEI)，指示该第一消息关联的一个或多个PO是否需要监听。当UE通过检测第一消息确定后续PO处没有寻呼时，UE可以处于睡眠状态；当UE通过检测第一消息确定后续PO处有寻呼时，UE才处于活跃态，去PO处接收寻呼调度信息，进而接收该调度信息调度的寻呼消息。
在没有寻呼时，有第一消息相比无第一消息会节省UE功耗；但是，在有寻呼时，有第一消息相比无第一消息会增加网络资源开销，增加UE功耗。
申请内容
本申请提供一种寻呼消息发送的方法和装置，能够降低有寻呼时终端设备的功耗。
第一方面，提供了一种寻呼消息发送的方法，该方法包括：确定寻呼消息的配置信息；在第一寻呼机会PO之前接收所述网络设备发送的第一消息，所述第一消息用于指示是否接收第一PO对应的寻呼消息；当所述第一消息指示接收所述第一PO对应的寻呼消息时，根据所述寻呼消息的配置信息，接收所述第一PO对应的寻呼消息。
基于上述技术方案，终端设备先确定寻呼消息的配置信息，当终端设备确定接收寻呼消息时，只需根据寻呼消息的配置信息去接收寻呼消息，无需再在PO处监听接收携带寻呼消息的调度信息的DCI，从而可以降低有寻呼时终端设备的功耗。
结合第一方面，在第一方面的某些实现方式中，所述方法还包括：接收所述网络设备 发送的第一配置消息，所述第一配置消息中包括所述寻呼消息的配置信息。所述第一配置消息是半静态发送的，所述第一PO在所述第一配置消息的配置周期内。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(global system of mobile communication，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分 多址(wideband code division multiple access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
在NR中，终端设备(user equipment,UE)所处的状态包括三种，无线资源控制空闲态(radio resource control_idle，RRC_IDLE)态、RRC非激活(RRC_INACTIVE)态及RRC连接态(RRC_CONNECTED)态。RRC_IDLE态，也可以称为空闲态，UE处于空闲态时，UE与基站的空口连接断开，不再保存上下文信息，UE只能接收基站发送的广播信息；RRC_INACTIVE态，也可以称为非激活态，UE处于非激活态时，UE与基站的空口连接断开，但是继续保存上下文信息，当UE由非激活态进入连接态时，基于保存的上下文信息，能快速地恢复到连接态；RRC_CONNECTED态，也可以称为连接态，终端设备处于连接态时，与网络设备建立空口连接，并根据空口连接与网络设备通信。
为了便于对申请提供的技术方案的理解，对寻呼流程和寻呼消息的接收进行简单描述。
处于RRC_IDLE态的UE与网络之间是不存在RRC连接的，对于RRC_INACTIVE态的UE，虽然与网络建立了RRC连接，但该连接是挂起的。当网络有下行数据需要发往处于RRC_IDLE或RRC_INACTIVE态的UE时，网络需要先通过寻呼(paging)流程来寻呼UE，以通知该UE建立或恢复RRC连接，然后才能进行数据传输。也就是说，paging是由网络发起的。在NR中，paging可由核心网发起，称为核心网寻呼(core network paging，CN paging)，也可由无线接入网(radio access network，RAN)发起的，称为RAN paging。
当UE处于RRC_IDLE态时，UE与基站(gNB)之间不存在RRC连接，且不存在该UE的RRC上下文，即gNB并不知道该UE的存在，从核心网的角度来看，此时UE处于连接管理空闲(connection management idle,CM_IDLE)态，例如，UE在接入和移动性管理功能(access and mobility management function，AMF)中的状态，UE与核心网之间不存在非接入层(non-access stratum，NAS)连接，但UE在所处的跟踪区(tracking area，TA)内已经被分配了一个唯一的标识，UE已经在AMF注册，且在AMF中存在上下文。当核心网需要向处于CM_IDLE态的UE发送下行数据或者下行NAS信令时，AMF会向UE所注册的所有TA内的所有gNB发送一条寻呼消息，然后gNB会通过空口发送一条paging消息以寻呼UE。处于RRC_IDLE态的UE收到paging消息后，通常会发起一个RRC连接建立过程以接收下行数据。如图1所示，出示了核心网寻呼UE的示意性流程交互图。
AMF主要负责和无线进行对接，接收和发送与UE通信的NAS消息，对终端进行注册、移动、可达、加密鉴权等管理，传递UE和SMF之间的NAS消息。
在RRC_INACTIVE态下，虽然UE和gNB同时保存着RRC上下文，但UE与gNB之间的RRC连接被挂起。同时，UE与核心网之间的连接依然得以保持，即从核心网角度看，UE此时处于CM_CONNECTED态。当网络需要给RRC_INACTIVE态的UE发送数据，例如下行数据到达时，由于RRC连接是挂起的，因此网络需要寻呼UE。又由于此时核心网认为UE处于连接态，因此核心网不会发起寻呼，而是由RAN节点，例如基站(gNB)来发起寻呼。
在RRC_INACTIVE态下，最后一个服务于UE的gNB节点会保存UE上下文并维持与核 心网之间的连接。如果最后一个服务于UE的gNB在UE处于RRC_INACTIVE态时从核心网收到了下行数据或与UE相关的NAS信令，那么该gNB会在UE所属无线接入网(radio access network，RAN)通知区(RAN-based notification area，RNA)包含的所有小区上寻呼该UE。如果RNA包含了相邻gNB上的小区，则该gNB会发送Xn应用协议(Xn application protocol,Xn AP)RAN paging消息到相邻gNB上，以通知相邻gNB在相应小区上寻呼UE。处于RRC_INACTIVE态的UE收到paging消息后，通常会发起一个RRC连接建立恢复过程以便接收下行数据。这里的RAN通知区为NG-RAN(例如gNB)管理的基于RAN的通知区域，且NG-RAN知道UE所属的RNA。如图2所示，出示了基站寻呼UE的示意性流程交互图。
处于RRC_IDLE或RRC_INACTIVE态的UE支持使用非连续接收(discontinuous reception，DRX)的方式来接收paging消息以降低功耗，该DRX又称为paging DRX，非连续接收周期(DRX cycle)由网络设备配置，其中，DRX cycle又称为寻呼周期。使用DRX，处于RRC_IDLE或RRC_INACTIVE态的UE只会在预先定义好的时间段“醒来”以接收paging消息，而在其它时间可以保持“休眠”状态并停止接收paging，这样就降低了功耗，提升了UE的电池使用时间。
对于paging DRX，RRC_IDLE或RRC_INACTIVE态的UE只会在每个寻呼周期内的某个特定寻呼机会(paging occasion，PO)上去尝试接收寻呼无线网络临时标识(paging radio network temporary identifier，P-RNTI)加扰的PDCCH。在NR系统中，PO是一组物理下行控制信道(physical downlink control channel,PDCCH)的监视时机(monitoring occasion)。一个PO可以包含多个时间片段(time slots)，例如，时间片段可以是子帧或正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。网络设备可以在PO中发送用于调度寻呼消息的下行控制信息(downlink control information，DCI)。另外，一个寻呼帧(paging frame，PF)是一个无线帧，可以包含一个或多个PO或PO的起点。终端设备在监听PO时，先确定PF的位置，然后再确定PF关联的PO的位置。需要说明的是，一个PF关联的PO可以从PF内开始，也可以从PF之后开始。UE可以根据寻呼配置参数以及UE_ID确定自己需要监听的PO位置，具体可参考NR和LTE现有技术，和本申请具体方案无关，这里不再展开描述。
图3出示了一种空口寻呼流程示意图，gNB收到CN或RAN触发的寻呼，会向UE发送寻呼DCI，寻呼DCI包括寻呼消息的调度信息，UE根据寻呼DCI接收寻呼消息。在此之前，gNB会向UE发送配置信息，配置信息里包括DRX cycle，PF偏置，PO起始位置，一个PF中包含PO的个数等。UE根据这些配置如何确定PO资源位置可参考NR现有寻呼机制，这里不再展开描述。
图4出示了一种终端设备接收寻呼消息的示意图。图示中UE按照DRX cycle监听PO，在图示中第一个PO处，UE没有监听到P-RNTI加扰DCI。UE继续监听图示中第二个PO处，UE监听到P-RNTI加扰DCI，并接收该DCI调度的寻呼消息。
在第一个PO并没有UE的寻呼，但UE不知情，仍然监听，如果UE能够提前知道第一个PO没有寻呼，这部分监听功耗可以节省掉。
目前，为了达到这个目的，针对处于RRC_IDLE或RRC_INACTIVE态的UE，在NR系统中计划引入第一消息，第一消息可以称为寻呼提前指示(paging early indication，PEI)。第一消息具体形式目前待定，可能的形式是DCI，或者类似于辅同步信号(secondary  synchronization signal，SSS)或跟踪参考信号(tracking reference signal，TRS)或信道状态信息参考信号(channel state information reference signal，CSI-RS)的序列。对于DCI形式，第一消息可能会采用一个或多个字段指示该第一消息关联的一个或多个PO是否需要监听。对于类似于SSS或TRS或CSI-RS的序列的形式，第一消息可能采用发送序列和不发送序列指示该第一消息关联的一个或多个PO是否需要监听，或者，第一消息可能采用不同序列指示该第一消息关联的一个或多个PO是否需要监听。这里只是列举了一些可能的形式，应理解本申请不对此做特别限定。
引入第一消息后，空口寻呼接收流程有一些变化，如图5所示，出示了另一种终端设备接收寻呼消息的示意图。UE在监听PO，接收寻呼DCI之前，需要先检测第一消息，确定需要监听第一消息关联的PO时，才执行后续监听PO，接收寻呼DCI，以及寻呼消息的行为。
如图6所示，出示了有/无第一消息时UE接收寻呼消息的示意图。如果gNB启用第一消息特性，对应图6中有第一消息的情况，gNB会在PO之前发送第一消息，UE通过检测第一消息确定后续的PO处是否有寻呼。当UE通过检测第一消息确定后续PO处没有寻呼时，UE可以处于睡眠状态，当UE通过检测第一消息确定后续PO处有寻呼时，UE才处于活跃态，去PO处接收寻呼调度信息，进而接收该调度信息调度的寻呼消息。有第一消息表示gNB启用第一消息特性，无第一消息表示gNB未启用第一消息特性或者gNB不支持第一消息特性。由于第一消息承载的信息比较少，UE检测第一消息的时长比较短，因此通过第一消息可以达到减少不必要的监听，进而实现UE节电。
如图6所示，在没有寻呼时，有第一消息相比无第一消息会节省UE功耗；但在有寻呼时，有第一消息相比无第一消息会有一些负面影响，见图6中黑色框选区域，此时有第一消息相比无第一消息会增加网络资源开销，增加UE功耗。
为此，本申请实施例提出了寻呼消息发送的方法，能够降低有寻呼时终端设备的功耗。
本申请主要应用于第四代(4th generation，4G)和5G移动通信系统，同时本申请也可以应用于其它的通信系统，只要该通信系统中存在实体可以发送信息，该通信系统也存在其它实体可以接收信息即可。如图7所示，出示了本申请实施例适用的一种通信系统架构示意图。基站和终端设备1至终端设备6组成一个通信系统，在该通信系统中，基站发送信息给终端设备1至终端设备6中的一个或多个终端设备。此外，终端设备4至终端设备6也组成一个通信系统，在该通信系统中，终端设备5可以发送信息给终端设备4和终端设备6中的一个或多个终端设备。
本申请涉及的网元有网络设备和终端设备。网络设备：用于从终端设备接收上行信号，或向终端设备发送下行信号；可以是LTE和/或NR的网络设备，具体的可以是基站(NodeB)、演进型基站(eNodeB)、5G移动通信系统中的基站、下一代移动通信基站(next generation Node B，gNB)，未来移动通信系统中的基站或Wi-Fi系统中的接入节点等。终端设备：终端设备是用户侧的一种用于接收或发射信号的实体，用于向网络设备发送上行信号，或从网络设备接收下行信号；主要包括手机、车、平板电脑以及智能音箱、火车探测器、加油站等传感器，主要功能包括收集数据、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。
如图8所示，出示了本申请实施例提出的一种寻呼消息发送的方法的示意性流程交互 图。该方法应用于网络设备寻呼处于空闲态或非激活态的终端设备。
该方法中终端设备确定寻呼消息的资源位置，寻呼消息的资源位置由双方约定或由网络设备配置，当第一消息指示有寻呼时，终端设备在确定的资源位置上接收寻呼消息，不需要通过接收DCI来接收寻呼消息。具体的过程包括：
810，网络设备向终端设备发送第一配置消息，该第一配置消息中包括寻呼消息的配置信息。网络设备可以通过第一配置消息发送寻呼消息的配置信息，当网络设备寻呼终端设备时，终端设备可以根据寻呼消息的配置信息接收寻呼消息，网络设备无需再在PO处发送携带寻呼消息的调度信息的DCI，从而可以降低有寻呼时网络设备的资源开销。
820，终端设备确定寻呼消息的配置信息。
具体而言，可选的，终端设备接收网络设备发送的第一配置消息，根据接收到的第一配置消息确定寻呼消息的配置信息。该第一配置消息中不仅包括寻呼消息的配置信息，还包括第一消息的配置信息和寻呼周期。其中，第一消息用于指示终端设备是否接收寻呼消息，第一消息可以称为寻呼提前指示(paging early indication，PEI)，可以称为提前寻呼指示EPI，，可以称为节能信号，也可以称为唤醒信号，这里对第一消息的名称不做限定。
应理解，第一消息的配置信息可以根据第一寻呼机会PO的配置信息确定，因此，第一配置消息中还可以包括第一消息关联的第一PO的配置信息。其中，第一消息的配置信息用于终端设备接收网络设备发送的第一消息，寻呼消息的配置信息用于终端设备接收网络设备发送的寻呼消息。因此，终端设备可以通过第一配置消息确定寻呼消息的配置信息，指示寻呼消息的配置信息的比特数相比于第一配置消息总的比特数而言，占比较小，在现有技术中终端设备也需要接收第一配置消息来确定第一消息和第一PO的配置信息，因此，终端设备接收寻呼消息的配置消息不会增加功耗，也不会增加新的接收流程。
可选的，寻呼消息的配置信息也可以由终端设备和网络设备提前约定，不需要通过配置消息发送。
830，网络设备在第一寻呼机会PO之前向终端设备发送第一消息，该第一消息用于指示终端设备是否接收寻呼消息。
可选的，第一消息的形式可以是DCI，采用一个字段或者多个字段指示终端设备是否接收第一PO对应的寻呼消息。
可选的，第一消息的形式可以是类似于SSS或TRS或CSI-RS的序列，可以采用发送序列和不发送序列指示终端设备是否接收寻呼消息，例如，发送序列指示终端设备接收寻呼消息，不发送序列指示终端设备不接收寻呼消息。也可以采用不同的序列指示终端设备是否接收寻呼消息。本申请实施例对此不做任何限定。
可选的，网络设备接收到其他网络设备发送的第二消息，例如核心网设备或无线接入网设备，该第二消息用于触发该网络设备发送第一消息。网络设备是根据接收到的第二消息发送的该第一消息。
840，终端设备在第一PO之前接收网络设备发送的第一消息。具体而言，终端设备根据第一消息的配置信息接收网络设备发送的第一消息；或者，终端设备根据与该第一消息关联的PO的配置信息确定出该第一消息的配置信息，再根据该第一消息的配置信息接收网络设备发送的第一消息。
终端设备根据第一消息，确定是否接收寻呼消息。若根据第一消息确定网络设备不发 送寻呼消息，则终端设备不会根据寻呼消息的配置信息去接收与该第一消息关联的寻呼消息；若根据第一消息确定网络设备发送寻呼消息，则终端设备根据寻呼消息的配置信息去接收与该第一消息关联的寻呼消息。
850，若网络设备向所述终端设备发送的第一消息指示接收与该第一消息关联的寻呼消息，则网络设备向终端设备发送与该第一消息关联的寻呼消息。若网络设备向所述终端设备发送的第一消息指示不接收与该第一消息关联的寻呼消息，则网络设备不会向终端设备发送与该第一消息关联的寻呼消息。
860，若根据第一消息确定接收网络设备发送的寻呼消息，则终端设备根据确定的寻呼消息的配置信息去接收与该第一消息关联的寻呼消息。应理解，终端设备不会再根据第一PO的配置信息去第一PO处接收寻呼消息的调度信息。
若根据第一消息确定不接收网络设备发送的寻呼消息，则终端设备不会去接收与该第一消息关联的寻呼消息。
其中，寻呼消息的配置信息可以包括以下至少一种：
(1)频域资源分配指示信息，该指示信息用于指示寻呼消息的起始资源块(resource block，RB)位置以及从起始RB开始占用的RB的个数；
(2)时域资源分配指示信息，该指示信息用于指示寻呼消息占用的时间单元的个数。时间单元可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，单载波频分多址(single-carrier frequency division multiple access，SC-FDMA)符号，时隙(slot)，微时隙(mini-slot)，子帧，或帧等；
(3)虚拟资源块(virtual resource block，VRB)到物理资源块(physical resource block，PRB)映射指示信息，该指示信息用于指示映射方式是采用交织方式还是非交织方式。例如，该指示信息对应1个比特，该比特置为0时表示VRB到PRB映射采用非交织的方式，该比特置为1时表示VRB到PRB映射采用交织的方式；
(4)编码和调制机制(modulation and coding scheme，MCS)，MCS用于确定调制阶数，目标码率；
(5)时域偏置指示信息。
如图9所示，出示了寻呼消息起始位置的确定方式示意图。时域偏置指示信息可以包括以下至少一种：
1)与寻呼消息关联的PO所在时隙的结束位置的偏置；指示的是寻呼消息起始位置相对于PO所在slot的结束位置的偏置，UE根据PO位置和该指示信息可以确定寻呼消息起始位置。应理解，UE需要确定PO的位置，如何确定PO位置可参考NR现有技术，这里不再展开描述。
2)与寻呼消息关联的PO所在时隙的起始位置的偏置；指示的是寻呼消息起始位置相对于PO所在slot的起始位置的偏置，UE根据PO位置和该指示信息可以确定寻呼消息起始位置。
3)与寻呼消息关联的第一消息所在时隙的结束位置的偏置；指示的是寻呼消息起始位置相对于第一消息所在slot的结束位置的偏置，UE根据第一消息位置和该指示信息可以确定寻呼消息起始位置。
4)与寻呼消息关联的第一消息所在时隙的起始位置的偏置；指示的是寻呼消息起始 位置相对于第一消息所在slot的起始位置的偏置，UE根据第一消息位置和该指示信息可以确定寻呼消息起始位置。
寻呼消息对应的时域偏置消息以第一PO或者第一消息的位置作为参考点，只需要配置一些偏置值即可，相比于按照没有参考点的方式进行配置，可以节省信令开销。
(6)传输块缩放指示信息，传输块缩放指示信息用于确定缩放因子，缩放因子用于确定寻呼消息最终传输块大小。根据缩放因子确定传输块方式可参考NR现有技术，这里不再展开描述。如表1所示，出示了一种传输块缩放指示信息的示例。
表1一种传输块缩放指示信息的示例
传输块缩放指示字域 缩放因子S
00 1
01 0.5
10 0.25
终端设备可以通过寻呼消息的配置信息获取接收寻呼消息必要的信息，从而使得第一方面方法的实施，即当终端设备确定接收寻呼消息时，只需根据寻呼消息的配置信息去接收寻呼消息，无需再在PO处监听接收携带寻呼消息的调度信息的DCI，从而可以降低有寻呼时终端设备的功耗。
考虑到NR支持多个波束(beam)传输，寻呼消息会在多个波束方向上发送，因此寻呼消息的资源配置可能包括多套配置，每一套配置对应一个波束方向。
多个波束传输中，为了减少信令开销，只有上述时域偏置信息需要每个beam单独配置，其它参数，各个beam相同，可以只需要配置一套。
gNB可以通过一个寻呼消息寻呼多个UE，RRC层的paging消息包含了被寻呼的UE列表，其内容如下，一个UE对应一个paging record，其中maxNrofPageRec表示一个寻呼消息包含的paging record的最大值，maxNrofPageRec＝32，也就是说一个寻呼消息最多可以寻呼32个UE。
考虑到不同时刻，被寻呼的UE的个数是不同的，即寻呼消息的内容在不同时刻有可能是不同的，此时如果一直按照一个固定的传输块进行传输，需要在寻呼消息增加很多的padding比特，传输效率低，还会影响寻呼消息的性能。
配置消息对于寻呼而言通常采用系统消息，因此寻呼消息的资源配置是静态或半静态配置，变化周期较长。且在每个PO之前有第一消息，通过第一消息动态调整寻呼消息的传输块大小是一种比较有效的方法。具体地，可以在第一消息中指示传输块缩放指示信息，此时第一配置消息中可以不携带传输块缩放指示信息。考虑到不同时刻，被寻呼的UE的个数是不同的，即寻呼消息的内容在不同时刻可能是不同的，此时如果一直按照一个固定的传输块大小进行传输，需要在寻呼消息增加很多的padding比特，传输效率低，还会影响寻呼消息的性能。基于上述技术方案，传输块缩放指示信息通过第一消息携带，将其它随时间变化不大的必要信息通过寻呼消息的配置信息承载，第一消息比寻呼消息的配置信息发送的机会多，从而使得寻呼消息的传输块大小可以通过第一消息以更加动态的方式进行调整，从而避免上述传输效率低，影响寻呼消息的性能的问题。
本申请实施例提供的技术方案中，终端设备先确定寻呼消息的配置信息，当终端设备 确定接收寻呼消息时，只需根据寻呼消息的配置信息去接收寻呼消息，无需再在PO处监听接收携带寻呼消息的调度信息的DCI，从而可以降低有寻呼时终端设备的功耗。
如图10所示，出示了本申请实施例提出的另一种寻呼消息发送的方法的示意性流程交互图。该方法应用于网络设备寻呼处于空闲态或非激活态的终端设备，具体过程包括：
1010，网络设备在第一寻呼机会PO之前向所述终端设备发送第一消息，第一消息携带第一指示信息和第二指示信息，第一指示信息用于指示终端设备接收第一PO对应的寻呼消息，第二指示信息用于指示第一PO对应的下行控制信道(physical downlink control channel，PDCCH)的位置信息，该PDCCH用于承载用于调度第一PO对应的寻呼消息的下行控制信息DCI。
第一指示信息可以称为寻呼提前指示PEI，可以称为提前寻呼指示EPI，可以称为节能信号，也可以称为唤醒信号，这里对第一指示信息的名称不做限定。可选的，第一指示信息的形式可以是DCI，采用一个字段或者多个字段指示终端设备是否接收与该第一消息关联的寻呼消息。可选的，第一指示信息的形式可以是类似于SSS或TRS或CSI-RS的序列，可以采用发送序列和不发送序列指示终端设备是否接收寻呼消息，例如，发送序列指示终端设备接收寻呼消息，不发送序列指示终端设备不接收寻呼消息。也可以采用不同的序列指示终端设备是否接收寻呼消息。本申请实施例对此不做任何限定。应理解，第一消息可以为PEI，该PEI中可以包括第二指示信息，本申请对此不做任何限定。
第二指示信息包括以下至少一种：PDCCH的时隙位置、PDCCH对应的控制信道元素(control channel element，CCE)聚合等级、PDCCH对应的CCE的起始位置和PDCCH在PDCCH对应的候选PDCCH中的索引。
调度寻呼消息的DCI对应的搜索空间有两种方式：第一种方式是复用SIB1的搜索空间，此时搜索空间ID为0，此时搜索空间由主信息块(master information block,MIB)配置；第二种方式是寻呼专用的搜索空间，此时搜索空间ID不为0。
以搜索空间ID为0的情况为例，详细阐述第二指示信息的指示方式。当SSB和CORESET 0的复用方式为pattern1时，pattern1指的是SSB和CORESET 0时域上不重叠，频域上，且SSB的传输带宽和CORESET 0对应的初始下行BWP在频域上有重叠。此时搜索空间0对应的候选PDCCH可以在两个连续时隙内实现。此时第一消息可采用1比特(bit)指示调度寻呼消息的DCI的时隙位置。表2为CCE聚合等级以及每个CCE聚合等级下候选PDCCH数量。

第一消息可以使用3bit联合指示CCE聚合等级，以及候选PDCCH索引。如表3所示。

Figure PCTCN2020140522-appb-000002
第一消息采用1bit指示调度寻呼消息的DCI的时隙位置，通过3bit联合指示调度寻呼消息的DCI对应的CCE聚合等级，以及该CCE聚合等级下的候选PDCCH索引。通过这种方式调度寻呼消息的DCI的资源位置就唯一确定，UE不需要执行盲检测。类比于现有技术，通过第一消息确定有寻呼时，第一消息中没有相关信令告知UE，UE需在不同聚合等级下盲检PDCCH，本实施例通过第一消息指示的方式，可以减少甚至消除盲检测PDCCH对应的能耗，取决于第一消息指示的粒度，如果通过第一消息唯一指定调度寻呼消息的DCI的候选PDCCH位置，UE就可以消除盲检测PDCCH对应的能耗，如果通过第一消息指示，调度寻呼消息的DCI的候选PDCCH位置相比于现有技术减少一半，UE就可以减少盲检测PDCCH对应的能耗。
类似地，搜索空间ID不为0的情况，第一消息中指示监听调度寻呼消息的DCI的时隙位置，CCE聚合等级，以及候选PDCCH索引。这三个参数可以独立指示，也可以联合指示。
可选的，网络设备接收到其他网络设备发送的第二消息，例如核心网设备或无线接入网设备，该第二消息用于触发该网络设备发送第一消息。网络设备是根据接收到的第二消息发送的该第一消息。
1020，终端设备在第一寻呼机会PO之前接收网络设备发送的第一消息。具体而言，终端设备根据第一消息的配置信息接收第一消息。
可选的，在网络设备向终端设备发送第一消息之前，网络设备还向终端设备发送了第二配置消息，第二配置消息中包括寻呼周期和该第一消息的配置信息。应理解，第一消息的配置信息可以根据第一寻呼机会PO的配置信息确定，因此，第二配置消息中还可以包括第一消息关联的第一PO的配置信息。
可选的，第一消息的配置信息也可以由终端设备和网络设备提前约定，不需要通过配置消息发送。
终端设备根据第一指示信息确定是否接收寻呼消息。
1030，当第一指示信息指示接收第一PO对应的寻呼消息时，终端设备根据第二指示信息确定第一PO对应的下行控制信道PDCCH的位置信息，PDCCH用于承载用于调度寻呼消息的下行控制信息DCI。
1040，若网络设备通过第一指示信息指示终端设备接收寻呼消息，即网络设备向终端设备发送寻呼消息，则网络设备在第一PO对应的PDCCH上向终端设备发送用于调度寻呼消息的DCI；若网络设备通过第一指示信息指示终端设备不接收寻呼消息，即网络设备不向终端设备发送寻呼消息，则网络设备不向终端设备发送用于调度寻呼消息的DCI。
1050，若网络设备通过第一指示信息指示终端设备接收寻呼消息，则终端设备在第一PO对应的PDCCH的位置上监听用于调度寻呼消息的DCI；若网络设备通过第一指示信息指示终端设备不接收寻呼消息，则终端设备无需在第一PO监听用于调度寻呼消息的DCI。
1060，若网络设备通过第一指示信息指示终端设备接收寻呼消息，则网络设备向终端设备发送与第一指示信息关联的寻呼消息；若网络设备通过第一指示信息指示终端设备不接收寻呼消息，则网络设备不向终端设备发送与第一指示信息关联的寻呼消息。
1070，若网络设备通过第一指示信息指示终端设备接收寻呼消息，终端设备根据监听的DCI接收与第一指示信息关联的寻呼消息；若网络设备通过第一指示信息指示终端设备不接收寻呼消息，则终端设备不会监听DCI，也不会根据DCI接收寻呼消息。
在本申请实施例提供的技术方案中，通过第一消息指示监听用于调度寻呼消息的DCI的时隙位置，CCE聚合等级，以及候选PDCCH索引，可以减少终端设备盲检测用于调度寻呼消息的DCI对应的候选PDCCH的数量，从而可以减少终端设备盲检测PDCCH使用的能耗，因此，可以降低有寻呼时终端设备的功耗。
